Many A Role
The great Jeffrey Tambor played three different roles on the show – a jack of all trades, eh. He played the part of a rich man, Winston Cromwell III, Dr. Tom Miller, a psychiatrist who was confused for a mental patient; and he played the part of the crazy dentist Dr. Phillip Greene, who got dumped by Terri.
Whoops
During the first few seasons, the opening and credits were shot at Venice Beach, which happened to be a last minute decision by producers. The first shot zooms in on ‘Jack Tripper’ riding his bike – a Venice shop-owner charged $100 for the camera crew to use his roof. Furthermore, the bike Jack rides belonged to a producer, and the girl Jack stares at which causes him to fall off his bike is actually Suzanne Sommers in a dark wig.
